McAllister and Burn (both ankle) and Webster (hamstring) were back in the starting line-up at Bramall Lane and are expected to start again in the return on Monday afternoon when the Glovers attempt to overturn a 1-0 deficit.
Matt Dolan and Nathan Ralph missed the first leg due to knee injuries but could return to contention while Reuben Reid is hoping to be involved after returning from his loan spell at Plymouth.
